Great boat for day-sailing or week-ending - this elegant, teak trimmed sailboat will be the envy of all in the harbor. Roomy cockpit and great layout in the cabin, with 6’ headroom and private v-berth head.

​Sails are in good shape, with Furlex roller furling. Interior and cushions in cabin are in nice shape as well. Boat is ably powered by Yanmar 1GM. Survey from 2015 and Supplement in 2016 available for review. Upgrades since 2015 include: Custom steel storage cradle built for boat Through hull fittings removed, restored, re-bedded 2019 New automatic bilge pump 2019 Toilet pump assembly replaced 2016 Engine rebuilt 2016 by Vermont Engine Service. Less than 40 hours since rebuild. New starter 2016 New batteries 2016 New Furlex line guard and line guide 2017

More about Cape Dory 25D: The Cape Dory 25D (D for diesel engine), introduced in 1981, is different in many ways from the Cape Dory 25 except it’s length-over-all - the 25D is an entirely different boat: wider, heavier, deeper, with inboard diesel engine, a dramatically different interior, and was priced at the time about 50% higher than the 25. According to Practical Sailor’s review, many say the 25D has better performance potential than the 25. The 25Ds rig is substantially more modern in design, with a mast 4 1/2’ taller than that of the 25, a J measurement over a foot longer, and a higher aspect ratio mainsail. The extra 6” of draft, 9” of beam, hard bilges, and 350 pounds of additional ballast make her quite stiff.

Give Emily a call/text at 802-316-6721 soon set up a time to see this beautiful boat - it won’t last long.

Calculations

Hull Speed
5.9 kn
Classic: 5.84 kn

Hull Speed

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL

5.91 knots
Classic formula: 5.84 knots
Sail Area/Displacement
16.4
16-20: good performance

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

Formula

SA/D = SA ÷ (D ÷ 64)2/3

  • SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D: Displacement in pounds.
16.37
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
40.1
>40: stiffer, more powerful

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Formula

Ballast / Displacement * 100

40.05
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
333.4
275-350: heavy

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
333.39
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
23.7
20-30: coastal cruiser

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
23.66
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
1.9
<2.0: better suited for ocean passages

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
1.86
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Later offered by C. W. Hood Yachts (1996?) as the OCTAVIA 25.
